Meta-prompting system for dynamic prompt generation using templates, standards, and patterns. USE WHEN meta-prompting, template generation, prompt optimization, or programmatic prompt composition.
Before executing, check for user customizations at:~/.claude/skills/CORE/USER/SKILLCUSTOMIZATIONS/Prompting/
If this directory exists, load and apply any PREFERENCES.md, configurations, or resources found there. These override default behavior. If the directory does not exist, proceed with skill defaults.
🚨 MANDATORY: Voice Notification (REQUIRED BEFORE ANY ACTION)
You MUST send this notification BEFORE doing anything else when this skill is invoked.
Send voice notification:
curl -s -X POST http://localhost:8888/notify \
-H "Content-Type: application/json" \
-d '{"message": "Running the WORKFLOWNAME workflow in the Prompting skill to ACTION"}' \
> /dev/null 2>&1 &
Output text notification:
Running the **WorkflowName** workflow in the **Prompting** skill to ACTION...
This is not optional. Execute this curl command immediately upon skill invocation.
Leverages RenderTemplate.ts for eval prompt generation
Eval templates may be stored in Evals/Templates/ but use Prompting's engine

Uses Structure.hbs for workflow patterns

Best Practices
1. Separation of Concerns
Templates: Structure and formatting only
Data: Content and parameters (YAML/JSON)
Logic: Rendering and validation (TypeScript)
2. Keep Templates Simple
Avoid complex logic in templates
Use Handlebars helpers for transformations
Business logic belongs in TypeScript, not templates
3. DRY Principle
Extract repeated patterns into partials
Use presets for common configurations
Single source of truth for definitions
4. Version Control
Templates and data in separate files
Track changes independently
Enable A/B testing of structures

Philosophy: Prompts that write prompts. Structure is code, content is data. Meta-prompting enables dynamic composition where the same template with different data generates specialized agents, workflows, and evaluation frameworks. This is core PAI DNA - programmatic prompt generation at scale.
